Lots of people said that the stock heatsink that comes with the SB processors (as well as some other CPUs before it) is trash. in your case, i wouldnt run prime 95 until i have installed that EVO cooler you say you have, there is no reason to run it really at this time if you are not running games. before your games arrive i would place that EVO on and OC as much as you think you should or your goal is, and now when your games arrive you can just install them and run them right away. good luck

I don't know about other people, but I OC'd the pizz out of my 2500k on the stock cooler.. it took me all the way to 4.2ghz before the temps got too high. I think something else might be wrong here because his gaming temps are fine.

Another reason I didn't install it immediately cuz the intructions on the CM website are hard for me to understand.

like others have said, there videos how to install hyper 212+/evo in youtube, if you dont like reading the manual... its actually easy, if I may ask I think you dont know how to un-install the stock heatsink also LOL just kidding
